An image display device includes a display panel, a plurality of light emitting elements, a reflective sheet, and a first optical sheet. The display panel displays an image on a front face of the display panel. The light emitting elements are disposed along one edge of the display panel. The reflective sheet is disposed opposite a rear face of the display panel. The reflective sheet reflects light from the light emitting elements toward the rear face of the display panel. The first optical sheet is disposed between the display panel and the reflective sheet. The first optical sheet has a plurality of protrusions on a face of the first optical sheet that is opposite the reflective sheet. The protrusions have ridgelines extending along a direction that is different from a direction in which the one edge of the display panel extends.
